Never mind - I think I have it - needed to replace uses of
cpp_dec_float_max_digits10 with cpp_dec_float_total_digits10 which does what
it says, where as cpp_dec_float_max_digits10 doesn't anymore. With that
change the tests I've run pass so far.... but they're still running.

Maybe we should rename cpp_dec_float_max_digits10 to something else? BTW,
what's the logic behind the +1 in defining that one? Not that it makes much
difference either which way.

Cheers, John.
